450 quakes at Yellowstone National Park

Yellowstone
Supervolcano is hit with a second cluster of quakes: Number jumps to
more than 450 in the last 7 days biggest being mag 4.5

The
cluster of quakes in Yellowstone Park has now been joined with a
second cluster as over 450 small and mid level quakes have have been
recorded in the famous park in the last seven days.

26
of these quakes have been above magnitude 2.5 with the biggest being
magnitude 4.5.

The
supervolcano has been rumbling with a series of more than 450
recorded since June 14h.

The
University of Utah Seismograph Stations reports that an earthquake
of magnitude 4.5 occurred at 06:48 PM on June 15, 2017 (MDT).

The
magnitude 4.5 was the biggest quake at the super volcano since 2014.

Wikipedia
claims the
last full-scale eruption of the Yellowstone Supervolcano, the Lava
Creek eruption which happened approximately 640,000 years ago,
ejected approximately 240 cubic miles (1,000 km3) of rock, dust and
volcanic ash into the sky.

Geologists
are closely monitoring the rise and fall of the Yellowstone Plateau,
which has been rising as fast as 0.6 inches (1.5 cm) per year, as an
indication of changes in magma chamber pressure.

The
upward movement of the Yellowstone caldera floor between 2004 and
2008 — almost 3 inches (7.6 cm) each year — was more than three
times greater than ever observed since such measurements began in
1923. From 2004 to 2008, the land surface within the caldera moved
upward as much as 8 inches (20 cm) at the White Lake GPS station. By
the end of 2009, the uplift had slowed significantly and appeared to
have stopped.
